EA Games' chief financial officer may have given away the Xbox One's install base during a financial call.

CFO Blake Jorgensen claimed that 55 million next-gen consoles were currently out in the wild with consumers.

Subtracting Sony's public quote of 36 million PlayStation 4 units sold suggests an Xbox One install base of 19 million.

Microsoft does not share Xbox One sales figures, instead promoting the number of active Xbox Live accounts, of which there are 48 million.

Despite lagging behind Sony's current-gen sales figures, the Xbox One is outpacing the Xbox 360 at this point in its product life cycle.

Indeed, Jorgensen said that the generation's sales as a whole "exceeded virtually everyone's forecast for the year and now almost 50 percent higher than previous console cycle," and described the console environment as "very positive."
